CPUM 209-595-067-121 CPU Card
Description:
The CPUM CPU card is a rack controller that acts as a system controller.
The modular, highly versatile design of the CPUM means that all rack configuration, display and communications interfacing can be performed from a single card in a “networked” rack. The CPUM card acts as a “rack controller” and allows an Ethernet link to be established between the rack and a computer running one of the software packages.
The CPUM front panel features an LCD display that shows information for the CPUM itself and for protection cards in the rack. The SLOT and OUT (output) keys on the CPUM front panel are used to select which signal to display.
The CPUM card consists of a carrier board with two PC/104 type slots that can accept different PC/104 modules: a CPU module and an optional serial communications module.
All CPUM cards are fitted with a CPU module that supports two Ethernet connections and two serial connections. That is, both the Ethernet redundant and serial redundant versions of the card.
The primary Ethernet connection is used for communication with the software via a network and for Modbus TCP and/or PROFINET communications. The secondary Ethernet connection is used for Modbus TCP communications. The primary serial connection is used for communication with the VM600 MPSx software via a direct connection. The secondary serial connection is used for Modbus RTU communications.
Optionally, a CPUM card can be fitted with a serial communications module (in addition to the CPU module) in order to support additional serial connections. This is the serial redundant version of the CPUM card.
The CPUM rack controller and communications interface card pair is recommended for applications using multiple monitoring cards in the rack.
